WordPress Modifications

I am looking into buying the following theme. [url removed, login to view]

I would like to make the following modifications to it. (If all are possible)

only need homepage menu - hide all other pages

hide clients (just for now)

Changes the side information of the detail image to

1. Name of Theme

2. Download Now for free (with download button and enable the ability for the customer to download a file. The customer must input email address before download completes.)

3. We Customize for only $[url removed, login to view] (When the customer clicks this - i want a contact box with 3 or 4 fields. (Would love to add the feature that when the form is complete they click submit and checkout- where they can checkout via paypal - only 1 price for all items)

Add deeplinking so that each item has it’s own custom URL (i.e. [url removed, login to view])

Thanks for the project opportunity. I would very much happy to place my bid on your project and I think all your requirement meet with my skill and expertise level.
